Oh, absolutely, they can be. I'm lucky in that mine provides decent flexi-time. I can start any time between 7:30 and 10:00, take lunch from 11:45 to 2:30 and leave between 3:30 and 6:00. So if I want a 65 minute lunch break I can have it - so long as my times add up in the long run. I'm in charge of being responsible for my timekeeping, which is how it should be.
